Elantra Hybrid
For the first time ever, a hybrid powertrain has been added to the Elantra lineup. Elantra Hybrid demonstrates Hyundai’s commitment to expanding its eco-focused lineup of products. The new Elantra Hybrid will feature a 1.6-liter GDI Atkinson-cycle four-cylinder engine. Elantra Hybrid’s permanent-magnet electric motor delivers 32 kW powered by a lithium-ion-polymer battery with 1.32 kWh of capacity positioned under the rear seats. The 1.6-liter GDI engine combined with the electric motor in Elantra Hybrid delivers a total system output of 139 horsepower and up to 195 lb-ft of torque. This engine mates with Hyundai’s quick-shifting, six-speed, dual-clutch transmission–differentiating Elantra Hybrid from its key competitors because of its more dynamic and engaging driving experience. The high-efficiency electric motor has an electric only driving mode that delivers instantaneous torque at low speeds, with available power-assist at higher vehicle speeds. The 2021 Elantra Hybrid is projected by Hyundai to have a combined estimated fuel economy rating of more than 50 MPG (with EPA certification pending in late 2020).
Engine Performance
The Elantra SE, SEL, and Limited offer the 2.0L MPI Atkinson Cycle engine that also has a focus on fuel economy. This engine generates 147 horsepower @ 6,200 RPM and 132 lb.-ft. of torque @ 4,500 RPM. These models are projected by Hyundai to achieve a best-in-class combined fuel economy rating, an improvement over previous models, due in part to an Intelligent Variable Transmission (IVT) (based on comparison of specifications on manufacturer’s websites at the time of press release issuance).
Intelligent Variable Transmission Mated to a 2.0L Engine
Hyundai’s IVT provides superior efficiency and simulates gear shifts like those in the automatic transmissions that customers are used to. This transmission performs continuous shifts by the modulating pressure of the transmission’s pulley, depending on driving conditions and driver inputs. It uses a wide-ratio pulley system, which provides a broader ratio of operation compared with its competitors. This allows for improved fuel economy at higher gear ratios and improved performance at lower ratios.
As opposed to a more common push belt, the IVT takes advantage of a chain-design belt that improves fuel efficiency by an additional 1.2 percent compared with conventional belt systems.
Hyundai’s new Shift Control Strategy used by the IVT improves linearity between driver inputs, vehicle behavior and acceleration. Shift response closely replicates automatic transmission step shifts.
